Plastic composition for toys, novelty items and arts and crafts

Abstract

A composition comprising a polyvinyl acetate homopolymer emulsion, glyceryl triacetate, silicon, epoxidized oil, talc, fumed silica and dextrin exhibiting remarkable molding, coloring and printing properties for used as novelty items, activity toys and molding compounds. This composition is also for use as an artist's tool, transfer and printing medium, as an exercising device and for art therapy. The molded object, after exposure to air, becomes dry and will remain flexible and permanent, including fine detail and brilliant colors. The composition may contain suitable food dyes, which allows the color to be transferred from the compound to paper, canvas, fabric and wall. The color print dries instantly. Luster and pearlescent pigments brushed on the surface of the molded objects gives the appearance of cast precious metal.
